No, he's not saying that at all. This is what he said;
"The writing down by the DJ wouldn't work for me. With 2 and a bit minutes records and people up on stage for requests, I don't have time. If I've been upstairs at the 100 Club working or just extra dozy, I ask someone who's stationed themselves at the front of the stage most of the night."
And by that he means for him personally, it wouldn't work because he's busy running the venue as smoothly as he can, such that he doesn't get to hear everything that gets played before he does his spot, so he asks others what has been played in order to avoid playing something that has already been played.
Now when he's a guest DJ, to the best of my knowledge, he normally turns up early, partly to listen to what's being played for a feel of what's working and also to avoid where possible playing something already played earlier, but the real truth is he'll have you believe, so that he can get pissed sooner.
